environment, although that mode is supported if needed due to user preference or application-
specific reasons. For target software, the target .rar file installs in the “mCPU_target” subfolder
under the main Signalogic folder on a Linux machine, as shown in Figure 4-1 above and Figure
4-2a below.

Note in Figure 4-2a above, RTAF software is stored on the “mCPU_target” subfolder, meaning
multicore CPU or other target hardware. This naming convention refers to run-time software for
multicore CPU or other target hardware; e.g. CIM accelerator, DSP card, video or telecom card,
network processing card, neural net card, etc. Note that the various supported multicore CPU
and other target hardware types are collectively referred to throughout the User Guide as
"targets", and code that runs on the target as executable target code and files, or "run-time" code.
For older generation SigC641x processor software, the target .rar file should be installed
(unzipped) on a WinXP or Win7/8 machine, to the C:\ directory. This allows all project file and
subfolder references inside the .rar file to remain intact. CCS3 and CCS5 project files and
DSPBIOS and SYSBIOS configuration files (.tcf and .cfg files, respectively) are provided.
For SigC641x modules, the target software folder hierarchy is shown in Figure 4-2b below.
